i To all where it 11mg; concern .Brooklyn, city, county,

Be it known that we, Jouu J. Gniinnn and ARTHUR A. WEBER, citizens of the United States. and both residing in the borough of and State of New York, and whose post-office addresses are, respectively, No. 80-1 Classon avenue, borough of Brooklyn, cit of New York, and No. 903 East 'lhirteenth street, borough of Brooklyn, cit oi llew York, have invented certain new and useful improvements in Tire-Spreaders, of which the following is a specifiu'tiori.

This invention relates to a tire spreader adapted for use in connection with automobile and other rubber tires, one object being: to provide a. device of the above class which is simple oi 'construction,easily manipulated. and inexpensive.

A further object being to provide a device as above described by which an automobile or other rubber tire may be opened at any desired point and retained in such open condition While repairs are being made.

The tire spreader comprises a new and improved construction and arrangement of parts which enables the user to fold the device into compact form when not in use, and is also adjustable to accommodate all sizes of tires now in general use.

A further object of the invention resides in the provision of rollers of novel construe tion to receive the edges of the tire during the repairing operation.

In the drawings similar reference charactors are employed to designate corresponding parts throughout the several views and in which Figure 1. is a plan View showing our improved spreader in operative position on a tire. Fig. 2. is an edge view the spreader. Fig. 3. is a partial cross section on the line 3-3 oi i. Fig, at. is a plan view of the spreader-folded, l ig. 5 shows a slightly modified form.

In the drawings an autoniohile ire is shown at 10, having the usual bead or The spreader is shown at l2 and. cou'ipr' l, :1 bar 13, having upwardly turned ends i l, piovided with right angle perforated. e7-:- tensions l5, formed wraith stop shoulders H).

.livotcd to the extensions iii, are linlearms 17, having pins 18, which engage the shoul ders 16 when said link-arms are swung outwardly into operative position, and the outer or l'ree ends of the link-arms 17, are slotted as at 19, to adjustably receive threaded pins 20, provided with wing-nuts 21. The pins have shoulders 22., bearing against the under side of the link-arms and beyond the shoulders the pins are unthreaded and each receives a roller 23, provided with a flange 23 anda circuniierential groove or recess 24, shaped to provide a shoulder and a divergent wall 24", adapted to receive the bead edges of the tire in interlocking relation as shown in Fig.

The pivot joint between the bar 13 and link-arms 1T isconstituted by thrcadedpius 25, having wingaiuts 26, bearing on the links, and the opposite ends of the pins 25, carry rollers 27, similar to the rollers 23, said rollers being retained in position on the pins 20 and 25, by cotter pins or other suitable means It will be understood that the bar 13, and link-arms 1.7, pivoted thereto, collectively constitute a U shaped frame and in Fig. 5 of the drawings we show a spreader comprisir-iggrollers as above described carried by a U shaped frame 28 of one-piece construction which for somework be prefez-red to the construction shown in Figs. 1 to 4, inclusive Our improved spreader is particularly adapted for use when inspection of the in side oi" the tire is desired for the reason that when the device is once in position it may be rolled amend the tire structure by reason of the interlocking relation ot' the rollers with the bead edge wration of. the spreader the parts in the o; are folded. into the position shown in Fig.

I 4, the smaller or outer ends of the rollers are inserted into the tire opening until. the

flanges 23 hear thereon, when the lillkllill'lfi LT, are tn-own outward until the pins if strike the shoulders HS, when the tire is tulip open. 'll-ie spreader should he placed on the tire so that the puncture or part to he repaired is arms so space.

lla vino thus described our invention what We claim and desire to secure by Letters Pat out is 1. .ln a tire spreader, a frame and rollers mounted thereon to engage the bead ties of the tire tor the purpose specified.

2. in a tire spreader, a U shaped frame having rollers to engage the tire edges as described.

about midway between the hole 3. In a tire spreader, a frame having ecljustnlole rollers to engage the tire edges fer the purpose specified.

4. In a tire spreader, a frame 21ml grooved mllers carried thereon fer the purpose [leseribei 4 I 5. In 51 tire spreader, a frame comprising e bar and link-arms pivoted 'theree tW-e pairs ef rollers mounted on said frame one roller of each pair being adjustable toward and from its ebmpanien for the purpese described. 6. In a, tire spreader, a frame censisting of a central berend link-arms pivoted hereto, groevecl rellers arranged in pairs, one roller of each peir'heing zidjustably meunted on the link-arms and means fer limiiiiig the outward movement'e-f :said linlaerms as shown and described.

7 A tire spreader comprising a frame and rollers mounted thereon, each of being shaped to provide a flange, a eircu1nferential groove and e diverge-m Wall adapted' to receive the tire edges in interlocking relation.

8. A tire -s reader comprising a frame having pivotal ends and grooved rollers, the

said rollers memes ends of, the central porition of hire fre.

11W upwardly turned and having geer' h r t angle extensions to which the she frame ere pivoted. as shewn serihecl.
